Abstract
Provided is a liquid crystal display device including: pixels that are provided in a row direction and a column direction in which data signal lines extend, the pixels each including a plurality of pixel electrodes, in a pixel, in an nth frame, a pixel electrode being electrically connected to a data signal line, and in the frame, the plurality of pixel electrodes being electrically connected to each other and being electrically disconnected from the data signal line. This allows an improvement in viewing angle characteristic of a liquid crystal display device.
